"It is with great shock and deep sorrow that we have learned of the passing of our Miss Austria 2024, Lucia Sisic," the statement read in German.
Sisic continued to hold the Miss Austria crown because no new competition had been held since her victory in 2024, according to Austrian newspaper Die Presse.
"Dear Lucia, you will always remain a part of our Miss Austria family. Rest in peace," the Mission Austria's post concluded.

Sisic's medical history: What happened to her?
According to a report by local outlet Oe24, Sisic had lived with a heart valve defect since birth and underwent seven heart surgeries.
One of her most serious surgeries, in 2017, reportedly required doctors to resuscitate her. The procedure also left her with nerve damage in her left leg and foot, forcing her to relearn how to walk.
Her congenital heart valve defect required medical care from shortly after she was born. Sisic underwent her seventh procedure in late 2025 and later shared an update with her Instagram followers, expressing relief that the operation was behind her.
